BACKGROUND

A digital image that includes visual information may be rotated such that one or more dimensions of the digital image (e.g., a width of the digital image, a height of the digital image, and/or the like) may change to ensure that the visual information is maintained (e.g., the visual information is not lost due to cropping the digital image, resizing the digital image, and/or the like).

SUMMARY

According to some possible implementations, a method may include capturing, by a user device, an image, the image including an object, wherein the object has an angle of orientation in relation to the image. The method may include identifying, by the user device, the object, wherein identifying the object includes determining an outline of the object. The method may include determining, by the user device, a first center point of the object and the angle of orientation. The method may include rotating, by the user device, the image based on the angle of orientation, wherein rotating the image based on the angle of orientation includes changing one or more dimensions of the image. The method may include determining, by the user device and after rotating the image, the one or more dimensions of the rotated image, and calculating, by the user device and after rotating the image, one or more offset values associated with changing the one or more dimensions of the rotated image. The method may include determining, by the user device and after rotating the image, a second center point of the object based on the first center point and the one or more offset values, and performing, by the user device, an action related to the rotated image based on determining the second center point of the object.

According to some possible implementations, a user device may include one or more memories, and one or more processors, communicatively coupled to the one or more memories, to capture an image including an object, wherein the object has an angle of orientation relative to the image. The one or more processors may receive information concerning a first center point of the object and the angle of orientation, and may determine a first value associated with a height of the image and a second value associated with a width of the image. The one or more processors may rotate the image based on the angle of orientation, and may determine, after rotating the image, a third value associated with the height of the rotated image and a fourth value associated with the width of the rotated image. The one or more processors may calculate, after rotating the image and based on the first value, the second value, the third value, and the fourth value, one or more offset values. The one or more processors may determine, after rotating the image, a second center point of the object based on the first center point and the one or more offset values, and may perform an action related to the rotated image based on determining the second center point of the object.

According to some possible implementations, a non-transitory computer-readable medium may store instructions that include one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to capture an image including a document, wherein the document has an angle of orientation relative to the image. The one or more instructions may cause the one or more processors to obtain information concerning a first center point of the document and the angle of orientation, and to determine a first height of the image and a first width of the image. The one or more instructions may cause the one or more processors to rotate the image based on the angle of orientation, and to determine, after rotating the image, a second height of the rotated image and a second width of the rotated image. The one or more instructions may cause the one or more processors to calculate, after rotating the image and based on the first height of the image, the first width of the image, the second height of the rotated image, and the second width of the rotated image, one or more offset values. The one or more instructions may cause the one or more processors to determine, after rotating the image, a second center point of the document based on the one or more offset values, and to perform an action related to the rotated image based on determining the second center point of the document.

DETAILED DESCRIPTION

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

Some entities (e.g., financial institutions, such as banks and/or the like) permit account applicants, or customers, to capture images of verification documentation (e.g., government-issued identification (ID) cards and/or the like) and/or financial documentation (e.g., a check, a money order, and/or the like) using a user device (e.g., a smartphone), and submit the images over the Internet for validation. However, this can often be a frustrating process for a user, particularly if an entity's backend platform repeatedly rejects uploaded images for not meeting certain image quality standards. For example, the server may reject the image of a verification documentation if the verification documentation is not oriented in the image correctly. Furthermore, the amount of time required for a user device to capture an image, upload the image to the server, and process the image increases as the file size of the image increases. Moreover, as the image's file size increases, more data may be transmitted to the server than may be needed for the server to process the image.

Some implementations, described herein, provide a user device that is able to automatically capture an image including image data associated with an object, identify the object and an angle of orientation of the object relative to one or more reference axes (e.g., the x-axis, the y-axis, and/or the like of the image), rotate the image based on the angle of orientation so that one or more dimensions of the object align with the one or more reference axes (e.g., the x-axis of the image prior to rotation, the y-axis of the image prior to rotation, and/or the like), calculate a center point of the object, and perform an action related to the rotated image, such as cropping the rotated image around the object. In some implementations, the user device may detect the object in a field of view of a camera of the user device and capture the image. In some implementations, the user device may identify the object in the image and one or more characteristics concerning the object, such as a center point of the object, a height of the object, a width of the object, the angle of orientation, and/or the like. In some implementations, the user device may rotate the image based on the angle of orientation and change the one or more dimensions of the rotated image. In some implementations, the user device may calculate the one or more dimensions of the rotated image after rotating the image and may calculate one or more offset values associated with changing the one or more dimensions of the rotated image. In some implementations, the user device may calculate a center point of the object after rotation of the image and perform an action, such as cropping the rotated image around the object, based on calculating the center point of the object. In some implementations, the user device may send the cropped rotated image to a server device for processing, such as for verifying the cropped rotated image.

In this way, the user device optimizes determining a position of an object in a rotation corrected image, which enables the user device to perform pre-processing operations related to the image. In this way, the user device ensures that one or more dimensions of the object are aligned with one or more dimensions of the rotated image (e.g., the x-axis of the object aligns with the x-axis of the rotated image, the y-axis of the object aligns with the y-axis of the rotated image, and/or the like), which can facilitate an image pre-processing application, such as cropping the rotated image around the object. This also conserves computing resources, power resources, and memory resources of the user device that would otherwise need to be expended to perform image pre-processing where the one or more dimensions of the object are not aligned with the one or more dimensions of the original image (e.g. less computing resources, power resources, and memory resources are needed to perform a pre-processing operation where the one or more dimensions of the object are aligned with the one or more dimensions of the rotated image because less processing is needed to identify the boundaries of the object). In this way, the user device minimizes the file size of the pre-processed image, which shortens the amount of time to upload, and process the pre-processed image. In addition, this conserves computing resources, memory resources, and network resources, associated with a backend platform, such as a server, that would otherwise need to be expended to receive and process pre-processed images with a large file size.

FIGS. 1A-1E are diagrams of example implementations 100 described herein. Example implementation 100 may include a user device (e.g., a mobile device, such as a smartphone and/or the like) and an object, such as a document (e.g., a document that indicates identification information, a government-issued identification (ID) card, an employee ID card, a health insurance card, a transaction card (e.g., a credit card, a debit card, an automated teller machine (ATM) card, and/or the like), a check, a money order, and/or the like). In some implementations, the user device may include a camera (e.g., one or more cameras) configured to capture images, and one or more applications (e.g., provided by, or associated with, an entity, such as a financial institution (e.g., a bank and/or the like)) capable of facilitating image capturing. In some implementations, the user may activate the one or more applications on the user device to capture an image of the object.

As shown in FIG. 1A, and by reference number 102, the user device captures an image including image data associated with an object. In some implementations, the one or more applications may instruct the user to position the user device over the object for the user device to capture the image including the object. In some implementations, the user may point the camera of the user device at the object and the camera of the user device may capture the image. In some implementations, the user device may detect the object in a field of view of the camera of the user device and automatically capture the image including the object based on detecting the object in the field of view of the camera. In some implementations, capturing the image includes saving the image in memory as an image file with a file size. In some implementations, the user device may cause a display of the user device to display the image as the user device captures the image (e.g., in real-time (or near real-time)).

In some implementations, the object has an angle of orientation relative to the image. In some implementations, the angle of orientation is relative to one or more reference axes, such as one or more dimensions of the image (e.g., an x-axis of the image, a y-axis of the image, and/or the like). For example, as shown in FIG. 1A, the one or more reference axes are the x-axis and the y-axis of the image and the object may have an angle of orientation that is oriented θ degrees from the one or more reference axes.

As shown by reference number 104, the user device (e.g., via an application executing on the user device) identifies the object in the image. In some implementations, the user device may process the image to identify the object in the image. For example, the user device may employ one or more computer vision techniques (e.g., a scale-invariant feature transform (SIFT) technique, a speeded up robust features (SURF) technique, a generalized robust invariant feature (G-RIF) technique, and/or the like) to process the image to detect and identify the object. In some implementations, processing the image may include determining one or more elements concerning the object, such as an outline of the object, a boundary outline of the object, a bounding box of the object, a bounding rectangle of the object, a bounding polygon of the object, a shape around the object, and/or the like. In some implementations, the user device may cause display of the one or more elements concerning the object as an overlay (e.g., an augmented reality overlay) on the image. For example, the user device may cause display of a rectangular shape around a government-issued ID card.

As shown by reference number 106, the user device (e.g., via an application executing on the user device) determines one or more characteristics concerning the object, such as a center point of the object, a height of the object, a width of the object, the angle of orientation, and/or the like. For example, where the object has a rectangular shape, such as a transaction card, the user device may determine a height of the object and a width of the object to determine the center point of the object. In some implementations, the user device may receive information regarding the one or more characteristics concerning the object. For example, the user device may receive information regarding the first center point of the object, the height of the object, the width of the object, and the angle of orientation from a server device (e.g., where the image was sent to the server device for processing), a separate application of the one or more applications (e.g., a particular object identification application) on the user device, and/or the like.

In some implementations, the user device may determine the one or more dimensions of the image. For example, the user device may determine a height of the image, a width of the image, a center point of the image, and/or the like. In some implementations, the user device may determine a first value associated with a height of the image, a second value associated with a width of the image, a third value associated with a center point of the image, and/or the like.

As shown in FIG. 1B, and reference number 108, the user device (e.g., via an application executing on the user device) rotates the image based on the angle of orientation. In some implementations, the user device may rotate the image around the center point of the image based on the angle of orientation. In some implementations, the user device may rotate the image by an angle of rotation that is equal to the angle of orientation, but in the opposite direction. For example, where the angle of orientation is θ degrees, the user device may rotate the image by an angle of rotation that is −θ degrees. In this way, the user device may rotate the image such that one or more dimensions of the object (e.g., an x-axis of the object, a y-axis of the object, and/or the like) align with the one or more reference axes (e.g., the x-axis of the image prior to rotation, the y-axis of the image prior to rotation, and/or the like). This may assist the user device in performing an action related to the object, as described below, such as cropping the object from the rotated image (e.g., the image after rotation).

In some implementations, rotating the image based on the angle of orientation may include changing the one or more dimensions of the rotated image so that the rotated image includes image pixels (e.g., pixels associated with the image before the user device rotates the image) and padding pixels (e.g., pixels that are added to the rotated image after the user device rotates the image). The user device may add the padding pixels to the rotated image to change the one or more dimensions of the rotated image to ensure that the image pixels remain part of the rotated image (e.g., the user device creates a bounding rectangle around the rotated image that includes the image pixels and fills in the empty spaces with the padding pixels). For example, as shown in FIG. 1B, the user device rotated the image based on the angle of orientation and increased the height of the rotated image and the width of the rotated image by adding padding pixels to the rotated image to ensure that all the image pixels remain part of the rotated image, to ensure that no part of the object is cropped, and/or the like. In some implementations, rotating the image and changing the one or more dimensions of the rotated image changes the file size of the image file saved in memory.

As shown by reference number 110, the user device (e.g., via an application executing on the user device) calculates the one or more dimensions of the rotated image after rotating the image. For example, the user device may determine a height of the rotated image, a width of the rotated image, a center point of the rotated image, and/or the like after rotating the image. In some implementations, the user device may determine, after rotating the image, a first value associated with the height of the rotated image, a second value associated with the width of the rotated image, a third value associated with the center point of the rotated image, and/or the like.

As shown in FIG. 1C and by reference number 112, the user device (e.g., via an application executing on the user device) may calculate one or more offset values associated with changing the one or more dimensions of the rotated image. In some implementations, the one or more offset values may include a height offset value based on the height of the original image (e.g., the image prior to rotation) and/or the height of the rotated image (e.g., the image after rotation), a width offset value based on the width of the original image and/or the width of the rotted image, and/or the like. In some implementations, the one or more offset values are related to an origination point of the original image, an origination point of the rotated image, and/or the like. For example, as shown in FIG. 1C, a width offset value (e.g., an x-offset) and a height offset value (e.g., a y-offset) are related to an origination point of the original image (e.g., a (0,0) origination point of the original image) and to an origination point of the rotated image (e.g., a (0,0) origination point of the rotated image).

In some implementations, the user device may calculate the one or more offset values by comparing the one or more dimensions of the original image (e.g., the image prior to rotation) and the one or more dimensions of the rotated image (e.g., the image after rotation). For example, the user device may calculate the height offset value based on a difference between the height of the image prior to rotation and the height of the image after rotation (e.g., a difference between the height of the original image and the height of the rotated image), the width offset value based on a difference between the width of the image prior to rotation and the width of the image after rotation (e.g., a difference between the width of the original image and the width of the rotated image), and/or the like. In some implementations, the user device may use the following example formulas to calculate the height offset value and the width offset value:

height offset value=(height_(AR)−height_(PR))/2

width offset value=(width_(AR)−width_(PR))/2

where:

AR indicates the image after rotation (e.g., the rotated image); and

PR indicates the image prior to rotation (e.g., the original image).

As shown in FIG. 1D and by reference number 114, the user device (e.g., via an application executing on the user device) calculates a center point of the object in the rotated image. In some implementations, the user device may calculate the center point of the object in the rotated image based on the center point of the object in the original image, the one or more offset values, the one or more dimensions of the original image, the one or more dimensions of the rotated image, and/or the like. For example, the user device may use the following example formulas to determine a horizontal value (e.g., an x-value) and a vertical value (e.g., a y-value) of the center point of the object in the rotated image:

x=(a.x−b.x)*cos(−θ)−(a.y−b.y)*sin(−θ)+b.x+xOffset

y=(a.y−b.y)*cos(−θ)+(a.x−b.x)*sin(−θ)+b.y+yOffset

where:

a is the center point of the object in the original image (e.g., the image prior to image rotation);

b is the center point of the image in the rotated image (e.g., the image after image rotation);

xOffset is the width offset value;

yOffset is the height offset value; and

θ is the angle of orientation of the object relative to the one or more reference axes.

As shown by reference number 116, the user device (e.g., via an application executing on the user device) performs an action related to the image based on determining the center point of the object in the rotated image. In some implementations, the action comprises a pre-processing operation, such as cropping the object out of the rotated image. In some implementations, the user device may crop the object from the rotated image based on the center point of the object in the rotated image and/or the one or more characteristics of the object. In some implementations, the user device may crop the rotated image around the object based on the center point of the object in the rotated image and/or the one or more characteristics of the object. For example, where the object is a government-issued ID card, the user device can calculate the coordinates of a border of the object based on the center point of the object in the rotated image, the height of the object, and the width of the object (e.g., calculate the coordinates of the four corners that comprise the rectangle-shaped government-issued ID card in the rotated image), which enables the user device to crop the object from the rotated image, crop the rotated image around the object, crop the object out of the rotated image, and/or the like. In some implementations, performing the action related to the image changes the file size of the image file saved in memory.

In some implementations, the user device may create an outline of the object based on the center point of the object in the rotated image and/or the one or more characteristics of the object. For example, the user device may create a rectangular outline of a health insurance card based on the center point of the health insurance card in the rotated image, the height of the health insurance card, and the width of the health insurance card. In some implementations, the user device may crop the object from the rotated image, crop the rotated image around the object, crop the object out of the rotated image, and/or the like based on the outline of the object.

As shown in FIG. 1E, the user device may perform additional and/or alternative actions after rotation of the image. As shown by reference number 118, the user device (e.g., via an application executing on the user device) may send a pre-processed image (e.g., the rotated image, the cropped rotated image, the rotated image with the object cropped out, image data concerning the object cropped from the rotated image, and/or the like) to a server device (e.g., the user device may upload the pre-processed image to an image verification server). For example, the user device may send the pre-processed image to the server device to verify content of the object in the pre-processed image. As shown by reference number 120, the server device may process the pre-processed image (e.g., the image verification server may verify the pre-processed image). For example, the server device may use a computer vision technique to extract data from the pre-processed image (e.g., extract data concerning the content of the object) and verify that the data is accurate by comparing the data and object-related information from a data structure. As shown by reference number 122, the server device may send a message to the user device regarding the pre-processed image (e.g., the image verification server may send a message to the user device regarding verification of the pre-processed image). For example, the server device may send a message to the user device indicating that the data extracted from the pre-processed image is accurate. As shown by reference number 124, the user device (e.g., via an application executing on the user device) may receive the message and cause display of information regarding the message on the display of the user device (e.g., the user device may present, for display, information indicating whether the pre-processed image has been verified).

By implementing the above techniques, the user device optimizes determining a position of an object in a rotation corrected image, which enables the user device to perform pre-processing operations related to the image. In this way, the user device ensures that one or more dimensions of the object are aligned with one or more dimensions of the rotated image (e.g., the x-axis of the object aligns with the x-axis of the rotated image, the y-axis of the object aligns with the y-axis of the rotated image, and/or the like), which can facilitate an image pre-processing application, such as cropping the rotated image around the object. This also conserves computing resources, power resources, and memory resources of the user device that would otherwise need to be expended to perform image pre-processing where the one or more dimensions of the object are not aligned with the one or more dimensions of the original image (e.g. less computing resources, power resources, and memory resources are needed to perform a pre-processing operation where the one or more dimensions of the object are aligned with the one or more dimensions of the rotated image because less processing is needed to identify the boundaries of the object). In this way, the user device minimizes the file size of the pre-processed image, which shortens the amount of time to upload, and process the pre-processed image. In addition, this conserves computing resources, memory resources, and network resources, associated with a backend platform, such as a server, that would otherwise need to be expended to receive and process pre-processed images with a large file size.

In some implementations, the user device may calculate the one or more dimensions of the image after rotating the image and may calculate one or more offset values associated with changing the one or more dimensions of the image. In some implementations, the user device may calculate a center point of the object after rotation of the image and perform an action, such as cropping the image around the object, based on calculating the center point of the object. In some implementations, the user device may send the image to a server device for processing, such as for verifying the image.

In this way, the user device optimizes determining a position of an object in a rotation corrected image, which enables the user device to perform an action related to the image. In this way, the user device ensures that one or more dimensions of the object are aligned with one or more dimensions of the image, which can facilitate an image processing application, such as cropping the image around the object. In this way, the user device minimizes the file size of the image, which shortens the amount of time to capture, upload, and process the image. This also conserves computing resources, power resources, and memory resources of the user device that would otherwise need to be expended to perform image processing where the one or more dimensions of the object are not aligned with the one or more dimensions of the image. In addition, this conserves computing resources, memory resources, and network resources, associated with a backend platform, such as a server, that would otherwise need to be expended to receive and process images with a large file size.
